In this thesis we investigate the extension of certain theorems
of additive number theory to three algebraic systems. A generalization
of a theorem by Cauchy and Davenport on the cardinality of the
sum of two sets of residue classes is given. We obtain and compare
estimates for the order of...
Allen Freedman defined a density space to be the ordered pair
(S,𝓕) where S is a certain kind of semigroup called an s-set and 𝓕
is a special type of family of finite subsets of S called a fundamental
family on S. Several properties for density spaces are
obtained, and...
The fate of hexachlorophene, a widely used bactericide, was
investigated using both intact male rats and rabbits and liver microsomes
from male rats. Hexachlorophene administered intraperitoneally
was found to be rapidly absorbed and distributed to all the
tissues of the animals. Excretion of the chemical in both species
occurred slowly,...
Detailed current profiles between the sediment-water interface
and 20 cm above it reveal a viscous sublayer in the bottom boundary
layer on the Oregon continental shelf. Data from three field experiments
are used to test fundamental assumptions about boundary layer
flow in the ocean. The first study, discussed in Chapter...
This multidisciplinary study integrates remote sensing, stratigraphy, siliciclastic and carbonate sedimentology, tectonics, and petrography of the Nisai, Khojak and Sharankar Formations to reveal the Paleogene depositional, diagenetic and deformational history of the Katawaz Basin.
Study of Landsat Thematic Mapper (TM) digital data shows that maximum discrimination of different rocks is...
